While his brother was gone, Jon activated the bow retarders--after snapping off the stern tubes. Then he sent the ship into a curve that would bring them back nearer the place where he wanted to land. But only part of his mind was doing that--the rest was wondering why there had to be so much fuss and detail in landing and taking-off with a ship. Why couldn't it be fixed so one man could navigate and pilot without all this bother? It ought not to be too difficult.... Jak was soon back with the recorder, and Jon showed him how to read it. Soon they located what seemed to be the center of that strange disturbance, and with Jak's help, Jon set the ship down on the sand, fairly close to where they thought that hoped-for metal or its ore might be found. When the two boys went into the living room, they told their mother what they had landed for, and that they were going out to look for the source of this excitement. "Is it really necessary?" she asked anxiously. "Mr. C. didn't say anything to me about any such thing. Haven't we got fuel enough to get home on?" "Sure, Mom," Jon hastened to explain. "But Pop thought this new stuff would be a lot more powerful than the fuel we're using. Said it ought to give us far greater cruising range with lots less storage space. If we found something of the sort, it would be a great contribution to space travel." "That's right," Jak added, "and if we do find such a thing here, miners will soon be flocking after it, and that'll mean _beaucoup_ credits for us." "Well," doubtfully, "I guess you know best. Your father seems to be growing better, and lets me feed him, even though he hasn't ever seemed to regain full consciousness. If you are sure this is what he'd do if awake, I suppose it is what you should do." * * * * * "Looks like a funny place for ore," Jon said as the two boys left the ship and started at a fast pace in the direction "Annie" had pointed out as the center of activity. "I'd have expected it to be in the mountains, not in a desert like this." "Yes, I was wondering about that." The elder brother shook his head slowly. "But you can tell there's something here. What is it we're really looking for? Oh, I know it's metal or ore of some kind," he added hurriedly as he saw Jon start a retort. "What I mean is, is it ore or natural nuggets, and is it radioactive, or what?" Jon grinned as he trotted along. "Don't really know much more than you. I know how to detect it, and I'll know it if we find it. But to tell ahead of time, I haven't the minnow of an idea." They had actually gone less than a quarter of a mile when the heat of the sun, reflected from the hot, white, desert sand, became almost unbearable. Finally Jak stopped, wiping the pouring perspiration from his face and neck. "We can't take much of this. Better go back and get our suits."
